I am having trouble understanding this question. I don't need every single value worked out I just want to understand what to do so I can work the rest out myself! The question is written exactly as writtten: The pK of an acid is 4.16. Calculate the pH of a solution of the acid if it is titrated to the following extents. Use the value associated with your student ID: extent of titration with NaOH, percent 0 1 2 3...

The picture below has species I-IV (teg = species in this case)
and traits/characteristics (a-j). Classify species I-IV based on
the traits (a-j) and draw a parsimony tree.
What effect would it have on your classification of the species,
if it was based on the amount of shared characteristics/traits?
Does it change anything if 0 (zero)...

Your answer is partially correct. A very long, hollow cylinder (radius 3.5cm) is formed by rolling up a thin sheet of copper. Electric charges flow along the copper sheet parallel to the axis of the cylinder. The arrangement is, in effect, a hollow tube...

I especially need help with understanding what the second
question is asking.
4. Use Hess' Law to calculate the enthalpy change (AHⓇt) for this reaction: (12 pts.) 6C(s) + 6H2(g) + 3029) → C6H12O6(S) + using the following equations: A. C(s) + O2(g) → CO2(g) B. H2(g) + 1/2O2(g) → H2O(g) C. C6H12O6(s) + 6020) — 6CO2(g) + 6H2O() D. H2O0) → H2O(g) AH'= -393.5 kJ AH'= -241.8kJ AH'= -2803.0 kJ AH°= +40.7 kJ Why is this change in enthalpy...

Hello, I am taking an electrical engineering lab course and I
really need help understanding the solution to this question:
Now this solution was marked as correct. Here are my
questions:
1) Could you please explain how they obtains the gain (Av) of 6
V?
2) Why did they substract 0.6 V from the gain?
If you could walk me through this solution step-by-step, I would
really appreciate it, thank you.
